Latte, a political blog, found in its logs this referrer: http://corp.google.com/~username/universalsearch/modes_v1/usability/rumsfeld.htm. As you can guess, this is an internal Google site. The blog is in the top 10 results for the query "Rumsfeld resigns" (albeit with an April Fool's Day prank), so his author thinks the blog is part of a test for a more comprehensive search engine, that will include fresher results like real-time news.
Indexing pages in (almost) real-time is probably the dream of every search engine. Until that's possible, Google might try to merge some of its indexes and create one interface for all the specialized searches. And that could be Google Universal Search.
